gas and boilers if not fixed correctly generally result in explosions
Gas is not a diy item so get in a professional gas fitter to fix the fault and be safe

At the opposite side of the burners from the igniter there is a small metal probe/rod situated where the flame would blow across it during operation. This rod is for flame verification so the gas valve will know that the gas is being ignited. Often that probe will get carbon built up on it which will cause the furnace to light but then abruptly shut off because "the probe doesn't know there is a flame there". A fine grit sandpaper works well to restore it's conductive ability. However, if the furnace runs for a while before it shuts off you could very well have an obstruction in the vent pipe or an obstructed indoor coil. If cleaning the flamerod doesn't remedy the problem, I strongly recommend a qualified serviceperson look at it! The furnace could well be turning itself off because something is getting too hot and coming back on when it cools. Good luck.

usually the codes are printed on the inside panel of the furnace, where the wire schematic is.

Usually on the inside cover of the door.

I would try the mfg. and see if they have a trouble shooting page and a teck guy

have you call the maker all they need is your model number

means the compressor is directly energised may be some one tried to repair but he jumped the thermostat.

You do not need a warranty card for your warranty to be valid. Your installing contractor provides the labor warranty and the factory provides the warranty on parts. All the necessary information to make a (parts) warranty claim is embedded in the serial number of your unit. As for a manual you should contact the installing company or visit the Weatherking (Rheem) site to request this information. www.weatherking.com
